TshaoTShAO and CorSt are located in 30 km South from Almaty at an altitude 2 735 meters above the sea level (Almatinskaya oblast, Karasayskiy rayon, Big Almaty Lake, Tien Shan Astronomical Observatory).

TShAO and CorSt are observational bases with good astroclimate up to 100 photometric nights per year, high transparency of atmosphere, negligible light pollution and turbulence (average FWHM=3″). Such astroclimate conditions and location near Almaty make TShAO and CorSt a convenient observational base for major astronomical research. Availability of automated 1-meter telescope and the Internet permits TShAO to participate in the international projects. 1-meter telescope is used for photometric investigation of variable stars in Milky Way, eclipsing systems with moving apsis line, eclipsing stars with pulsing component; programs on exoplanets and white dwarfs are being implemented.

Prospective modernization and automation of the second 1-meter telescope will expand TShAO opportunities.

TShAO relates to the strategic sites of space industry (Government of the Republic of Kazakhstan dated June 30, 2008 № 651).
